This was a nice map ya made here! It was short & simple, the level designing was also detailed! The only thing that could have been fixed was the metal fence at the beginning, it's a little off and doesn't connect to the other fences.
But still, this was a nice little level you made! Had fun playing it, although the lack of any info (description, base, etc.) made me suspect it was another Terry wad, but nope. Just a normal Doom map!
